My graduate work briefly describes steam boilers and steam installations. First part of my graduate work is about the basic characteristics, main components, fuel, water preparation, usability, work mode and the sole purpose of the steam engine.
Second part contains task description, startup of the spare boiler with the main boiler which is constantly working. It also contains the explanation why the spare boiler and the main steam generator one can not function at the same time together with detailed description of the steam boiler and the steam generator which combined represent the main focus of my graduate work.
The third part suggests conceptual solution-construction and the installation of the necessary system elements that allow simultaneous operation of the both boilers. It explained engineer technologies used, quality of the equipment installed, relevant rules and regulations of the profession, as well as the testings of the carbon steel seamless tube used for the modification of the steam engine.
Fourth part describes in details welding technology used during the upgrading of the steam system on the steam boiler, preparing the weld edge, basic and additional materials, welding processes (with detailed description of the TIG and SMAW welding), welding positions, laying layers and passages in the welding process and the quality control methods.
